TO ALL WHOM IT MAY CON CERN l Be it known that I, GEORGE L. WITSIL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement iri Churns; and I do hereby declare that the following is a full,

clear, and exa-ct description of the same, reference being had' to the annexed drawings, making part ot' this specification, in which- Figure l is a perspective view of the flasher; and Figure 2 is a vertical section. The same letters are employed in all the gures in the indication ot' the same parts. A is the body ot' the ordinary statilehurn; B is the cover, which is constructed with an annular opening through which the dasher passes. A. pin, B', passes horizontally across and through the centre ofthe cover. The

flasher C is a concave-convex plate with triangular openings vertically through vthe same. Above the dasher are four flanges, D, radiating from the handle, and having notches cut in their outer ends. The dasher-handle E is made hollow below the top of the cover, and through the shell I cut two spiral slots on opposite sides. The pin B passing through both slots gives a rotary motion to the dasher, alternately, in opposite directions with the vertical reciprocating action ofthe handle. At the upper end of the handle is attached a flange, F, at the base of a projecting pin, on which is loosely7 tted the eross-picec G, and above this a washer, H, is attached to the pin, so that the cross-piece shall be retained on the pin. This cross-piece is intended to be held in the hands of the operator, so that the handle and dasher may turn freely when at work. The hollow shaft is intended not only to give the alternating rotary motion to the dasher, but also to conduct atmospheric air downward into the cream, into which it will pass through the slots. The form of the dasher is such asto break thc globules of cream, and to collect the particles of butter, which latter operation is Afacilitated by the triangular openings through the dasher, and by the angular notches in the ends ofthe flanges. While I prefer the hollow handle, as described, with the two opposite spiral slots, the same ete'ct will be in part produced by employing a spiral slot passing entirely through a solid handle to receive the pin B', in the same manner as in the case of the .double slots in the shell of a hollow handle.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The dasher-handle, E when constructed with a spiral opening entirely through the same, in combination with the pin B, for giving an alternately rotary motion to the dasher with the vertical reciprocating action of the handle, substantially as described. I v

`2. The combination of the con'cavo-convex dasher C with triangular'openings and radial flanges D, having angular notches in their ends, with a device for giving a reciprocating, vertical, and alternating rotary motion to the flasher, substantially as and for the purpose set forth. v

3. The combination ofthe dasher-handle E, constructed as described, and the cross-piece G, when arranged to operate substantially as set forth.

In testimony whereof Ihave signed my naine to this specification in the presence of two subscribing witnesses.

GEORGE L. WITKSIL.
